Will this interfere with my trunk seal or weather stripping?

The AF-3 wing mounts to the trunk lid surface above the seal line. Verify your trunk gasket routing before mounting—most factory seals sit below the spoiler footprint, but inspect your exact trim to confirm clearance at the mounting points.

Should I use adhesive or drill through the trunk lid?

Mounting method depends on your preference and trunk construction. Adhesive-only installation requires thorough surface prep—sand and clean the mounting area to bare composite or plastic. Drill-through with fasteners offers permanent security but requires precision hole placement. Either approach works; choose based on your comfort level and whether you want to preserve a clean underside.

Will the spoiler stay stable at highway speeds?

Real carbon is rigid and won't flex or rattle once properly secured. The AF-3 design distributes wind load across the full wing profile. Ensure all mounting points are fully seated and fastened to spec—loose installation, not the spoiler itself, causes movement. Verify your mounting hardware is torqued evenly across all attachment points.
